Trinka review

Trinka targets a group Grammarly serves less directly: researchers, students writing theses and technical authors. It corrects against APA, AMA, ACS, AGU and IEEE style guides, runs technical spell checks, consistency checks and inclusive language checks, and proofreads Word and LaTeX files with tracked changes on paid plans. There is a native app for Microsoft Word. The free Basic plan includes 5,000 words of writing assistance a month in Lite mode. Premium gives full writing assistance in Lite and Power modes, all paraphraser modes and up to 120 editable proofread files a year, while plagiarism and citation tools run on credits. Premium Plus doubles credits and adds file translation in 30+ languages, and the Confidential Data plan adds an offline checker and compliance with SOC2, HIPAA, ISO and GDPR. Premium costs $48 a year, about $4 a month, and Premium Plus $75 a year. We compared documented features and published plan details.
